"First, they responded by phone within an hour of my requesting a quote through Angie's. The dispatcher, Bona, was friendly and knowledgeable, and she said that Fred could come out the next morning between 9-10am, which he did. Fred did a great job. He's very thorough and personable. He explained everything that he was going to do and the reasons for doing each thing, and then went over each item when he was finished. I was very impressed and definitely will use them again for future plumbing needs."

"Prime Plumbing provided excellent customers service from the beginning to the end. Rob was very thorough when he came out to provide estimate, financing options and gave good explanation of what was needed to replace my direct vent hot water tank for my condo. Rob was also the one who installed the hot water tank and did an excellent job. Direct vent hot water tanks are much more expensive than your standard hot water tank, so it was pricey. I initially found Prime Plumbing on Angie's list and I would recommend them for your plumbing needs. I'm a single female in my early 60's. I did end up using my own financing because their finance company interest rates were way too high for someone with excellent credit. Do rate comparison first."

"This plumber detected an issue under my toilet that the other 2 plumbers I got quotes from did not. His repair was excellent and will save me further money down the line, as he prevented a rotting issue with his repair. I felt that Kap was honest in his quote and advice and I was very happy with the results. I am going to call him again for future needs."

"When I used Jimmy Gusky's plumbing services 3 years ago, I was as pleased then as I am with this current job. He and his employees provide reliable service in a timely and professional manner. Hats off to James "The Plumber" and his assistant who performed my repairs."

"I spoke with 7 companies with Angieâ s list and a couple local. Companies wanted service fee just to come out. They also would not give me a idea of price. 2 plumbers showed up at the same time neither new other price. LAl at Suma Plumbing and Drain was great. Best news is he was super polite and hundreds of dollars less than the others. Win Win. Do yourself a favor contact him. If a company charges a service fee it is the wrong company. I have a new plumbing company."

Plumbing FAQs, answered by experts

If your toilet is still leaking after replacing the toilet flapper, then you may not have installed the toilet flapper correctly. Double-check that you have placed the flapper over the overflow tube correctly, and check the flapper chain is at the right length. If your toilet is still leaking, then you may have another problem on hand. For example, you may need to replace the toilet wax ring or replace the toilet fill valve if your toilet is wobbly and leaking from around the base.

Connected a water line to a refrigerator is an intermediate project that’s perfect for DIYers. If your fridge and sink already have a water line and need replacing, then this task will be even easier. However, if you’re installing a water line for the first time, it should still be a doable project to take on. You’ll just need to install an adapter to your sink before you can connect the water line.  

According to the Uniform Plumbing Code (UPC), the distance between your trap and the vent should be no more than 6 feet. For your vent to work properly, it needs to feed into the drain line within 6 feet of trapways that connect to it. Using this formula, you should be able to determine whether you will need multiple vent lines.

The lifespan of bathroom pipes is between 20 and 100 years. This is a wide range, so to narrow it down, it helps to know which type of material your pipes are made from. Copper and cast iron have the longest lifespan—between 50 and 100 years—while other materials, such as galvanized steel and brass, last for 50 years or less.

You should leave the water dripping when temperatures are below 20 degrees for three hours or longer or your power goes out in the winter. Leave the water dripping until temperatures are consistently above 20 degrees and you’ve checked for frozen pipes. With water movement in your pipes, ice is less likely to form, and your pipes are less likely to burst. The drip relieves pressure, preventing burst and leaking pipes.
